Description of the Related Art Conventionally, as a rubber bearing device for supporting a cross beam arranged in a direction perpendicular to the direction of a bridge axis, one having a structure in which the amount of expansion and contraction of the cross beam is absorbed by shear deformation of a rubber layer in the rubber bearing device. Are known. When a horizontal force distribution type rubber bearing is used at the end of a cross girder installed in a direction perpendicular to the longitudinal direction of the bridge, the amount of expansion and contraction in the direction perpendicular to the bridge axis (longitudinal direction of the cross girder) is extremely large. It may be larger than the amount of expansion and contraction in the axial direction. Conventionally, rubber bearings have a structure that absorbs the amount of movement of the structure installed on the rubber layer by the shear deformation of the rubber layer.To always correct the amount of expansion and contraction due to temperature change, preliminary shear deformation must be applied to the rubber layer. Must. However, due to the structure of the rubber bearing, it is difficult to apply preliminary shearing deformation in the direction perpendicular to the bridge axis. Furthermore, in the case of cross beams, especially steel cross beams, there is a problem that it is very difficult to install the cross beams to the pier because the cross beams expand and contract due to daily temperature changes, and the cross beams move due to camber, dead load and the like. Generally, the design is made with the direction perpendicular to the bridge axis fixed, but this may not be the case with independent columns (the piers in the direction perpendicular to the bridge axis become too large and difficult to design). Has invented an elastic bearing device for a horizontal girder bearing capable of adjusting the movement in the direction perpendicular to the bridge axis.

う問題がある。In the conventional rubber bearing device, the amount of expansion and contraction of the cross beam is absorbed by the shear deformation of the rubber material. The shear deformation increased, and the rubber material in this state was further subjected to a strong horizontal force such as an earthquake.As a result, the rubber material became less cushioning, and the rubber layer in the rubber bearing device might be damaged. There is a problem of inefficiency.

A lower portion of the horizontal center support member 3 of the lower support member 2 is fixed to an upper portion of the pillar 1, and an upward opening groove 21 is provided on an upper surface of the center support member 3 to provide elasticity such as rubber. A lower support projection 20 fixed to the lower surface of the lower metal support plate 5 of the movable elastic support 7 including the plate 4, the lower metal support plate 5, and the upper metal support plate 6 is connected to the upward opening groove 21 by a bridge shaft. The movable elastic bearing 7 is movably fitted in the longitudinal direction of the cross beam orthogonal to the direction, and furthermore, a sliding bearing plate 10 is interposed between the movable elastic bearing 7 and the central support member 3 to thereby move the movable elastic bearing 7 to the center support. The upper support member 9 is placed on the movable elastic support 7 and is fixed to the upper metal support plate 6.
After adjusting the relative position in the longitudinal direction of the cross beam orthogonal to the bridge axis direction with respect to the upward opening groove 21 and holding it, and then fixing the cross beam 8 to the upper support member 9, A method of installing an elastic bearing device for cross beam support, which releases the holding of the relative position with the lower support projection 20 in the longitudinal direction of the cross beam.

弾性支承装置の据付方法。4. A lower part of the horizontal center support member 3 of the lower support member 2 is fixed to an upper part of the pillar 1, and an upward opening groove 21 is provided on an upper surface of the center support member 3 to provide elasticity such as rubber. A lower support projection 20 fixed to the lower surface of the lower metal support plate 5 of the movable elastic support 7 including the plate 4, the lower metal support plate 5, and the upper metal support plate 6 is connected to the upward opening groove 21 by a bridge shaft. Movably in the longitudinal direction of the cross beam perpendicular to the direction and immovable in the bridge axis direction, and is movable by interposing a sliding bearing plate 10 between the movable elastic bearing body 7 and the central supporting member 3. An elastic support 7 is mounted on the central support member 3, and the upper support member 9 is mounted on the movable elastic support 7 and locked on the upper metal support plate 6,
Next, after adjusting the relative position of the lower bearing protrusion 20 in the longitudinal direction of the cross beam orthogonal to the bridge axis direction with respect to the upward opening groove 21 and holding the same, and then mounting and fixing the cross beam 8 to the upper support member 9 A method for installing an elastic bearing device for supporting a girder, which releases the holding of the relative position between the upward opening groove 21 and the lower bearing protrusion 20 in the longitudinal direction of the girder.
